Hello!
I have a Galaxy Note 3 SM-N900 that I got from a friend. When my friend gave it to me he still had all his stuff on it so I did a factory reset on the phone. After I reset it the phone had a null IMEI and an unknown baseband. I'm pretty sure the problem is with the modem as I've flashed the stock firmware on the phone several times, I've tried almost all the custom roms on the phone, I've even flashed a whole boatload of different modems.
One of the times I was at school I pulled out my phone to change my music and I noticed it had signal. The phone had signal in different parts of the school and it also had a working IMEI and a baseband. I called 911 to test if the phone worked and the call went through as if the phone never had an issue to begin with. I haven't been able to get any signal on the phone since then. I don't know what else to do and I was hoping someone could help me here! Thanks in advance for those who try to help me!
IMEI Standard answer is to restore your backed up EFS folder as per the faqs and guides .
You may well have a lose connection/ sim within the phone if its intermittent on .
Sadly I don't have a backup of my EFS. I had reset my phone from the settings menu so I didn't think that would cause any problems. Is there anyway I can get a backup of an EFS for the sm-n900 or are there any other solutions?

NO
You could try flashing a stock lollipop firmware .
Again, I've tried that multiple times already. My EFS folder should be fine if I got signal randomly. My sim contact isn't loose as when I got signal I didn't have a sim in the phone. I think the problem is my modem but if it is I don't even know which modem to use.
Modem for your location/ network .
How do I find the correct modem? I live in the US and my network is MetroPCS
Also, thank you for trying to help me. I honestly appreciate it.
Please help me anyone!
Hi,
Story: I bought F320L for 86$. The bad think was there is no IMEI in it. The seller didn't told me there is no baseband too. I was trying to repair it since 3 months... Finally i found this: http://forum.xda-developers.com/lg-g2/help/f320k-f320l-f320s-network-problem-t2921626 and it "worked". When I insert the sim card into phone, it can see the network and work with it for 5minutes. But I can't call nobody, recive calls, write sms, check how much money I have got.. Nothing. So when I flashed this baseband, I managed to restore IMEI with EFS Professional. I can restore Imei and ESN, but i can't restore MEID. In phone is IMEI and ESN. When I flashed rom "CloudyStock 2.8" with baseband from @Cloudyfa, it didn't worked. When I flashed this bb from @grandixximo, it worked, but like on stock: no calls etc. I was trying many providers like: P4, Plus, Orange (Polish providers). I think it can't be hw problem because phone can connect to network for maybe 5 minutes(and then it loses the network and trying to search). What can I do now?

I flashed the stock rom without knowing that i had to take the efs backup since the imei gets lost after downgrading. Now i have no signals, I've tried many ways to restore the signal but i couldn't succeed. I'm even unable to get the 3g signals back. Can anyone please help me out with this.
Hi,
I have Axon 7 mini B2017G and I have lost network signal.
This initially happened after updating firmware to EU (to get 7.1.1) I noticed sound not working. So I tried to root phone for TWRP and Lineage but that resulted in IMEI 0 for both IMEI's.
I have since restored both original IMEI but still cannot get signal for more than 30seconds after a full factory reset. Regardless of firmware, rooted or not rooted etc etc.
Seems I have lost important NV data while messing with Modems and restoring IMEI etc.
Can someone please do a full EDL backup with "Axon7_Mini_EDL_Tool" of All partitions (including modemst1, modemst2 fsg) so I can restore baseband configuration, modem partitions etc???
If that isn't an option for someone with the same phone as me, then can you please backup NV items as QCN file so I can try repair my network issue??
The idea i have is to restore ALL partitions from exact same model/version and then restore my original IMEI's in the hopes that I can once again register GSM network and use the phone.
Thank you
Sorted.

same happened to me after messing with network setting, SIM 1 now stuck on LTE mode only which has limited coverage in some areas. SIM 2 is working fine.
I read somewhere that if you downgrade to Marshmallow, it might solve your problem.
I don't know what to do :crying::crying::crying:
